Ok, first Maizy had constipation last week. A little pumpkin and colace did the trick. Now Jake at first looked like he was showing some of the same symptoms, but instead started having huge blowouts of diarhhea, first orange and mucus (sorry to be so graphic here guys, but it is the nurse in me) then after about l8 hours turned dark brown, still liquid. Gave small amounts of rice and a teaspoon of hamburger, which he ate, still drinking, still runnning around. Vet suggested pepto bismol last night, this morning at ll still has runny dark stuff, every two hours (making sleep a luxury). I guess we will have to go see her, but any more suggestions on how to deal with this? He is well supervised when out so I don't think he ate anything.
